js中substring截取字符串

在JavaScript中,可以使用substring()方法来截取字符串。该方法有两个参数,分别表示截取的起始位置和结束位置(不包括结束位置的字符)。如果省略第二个参数,则截取到字符串的末尾。例如:
var s = "http://c.biancheng.net/index.html";
var a = s.indexOf("c");
var b = s.indexOf("/", a);
var c = s.substring(a,b);
var d = s.slice(a,b);
通过上述代码,使用substring()方法可以截取到字符串中以第一个参数指定的字符为起点,到第二个参数指定的字符为终点(不包括终点字符)的子串。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
